Role of motivation to respond to provocation, the social environment, and trait aggression in alcohol-related aggression

Little attention has been paid to the motivation to respond to provocation and to the interaction between this motivation, alcohol, the drinking environment, and individual characteristics. Undergraduates at six Canadian universities (N = 1,232) read three vignettes describing conflict situations with social environmental manipulations while imagining themselves as either sober or intoxicated. Self-ratings assessed likelihood of assertive and aggressive responses and motivational indices of anger, offensiveness of the instigator's actions, and importance to respond to the provocation. Respondents also completed a measure of trait aggression. Multi-group structural equation models supported the hypothesis that perceived likelihood of reactive aggression is influenced by perceived alcohol intoxication, gender, trait aggression, social environmental factors, and motivation to respond to the provocation. In addition, a number of interactions were found among the predictors. These results provide insight into the types of factors that may influence aggression in drinking situations.     

Development and validation of the social information processing application: a Web-based measure of social information processing patterns in elementary school-age boys

The purpose of this study was to evaluate the psychometric properties of an audio computer-assisted self-interviewing Web-based software application called the Social Information Processing Application (SIP-AP) that was designed to assess social information processing skills in boys in 3rd through 5th grades. This study included a racially and ethnically diverse sample of 244 boys ages 8 through 12 (M = 9.4) from public elementary schools in 3 states. The SIP-AP includes 8 videotaped vignettes, filmed from the first-person perspective, that depict common misunderstandings among boys. Each vignette shows a negative outcome for the victim and ambiguous intent on the part of the perpetrator. Boys responded to 16 Web-based questions representing the 5 social information processing mechanisms, after viewing each vignette. Parents and teachers completed measures assessing boys' antisocial behavior. Confirmatory factor analyses revealed that a model positing the original 5 cognitive mechanisms fit the data well when the items representing prosocial cognitions were included on their own factor, creating a 6th factor. The internal consistencies for each of the 16 individual cognitions as well as for the 6 cognitive mechanism scales were excellent. Boys with elevated scores on 5 of the 6 cognitive mechanisms exhibited more antisocial behavior than boys whose scores were not elevated. These findings highlight the need for further research on the measurement of prosocial cognitions or cognitive strengths in boys in addition to assessing cognitive deficits. Findings suggest that the SIP-AP is a reliable and valid tool for use in future research of social information processing skills in boys.     

Sensitivity to reward frequency in boys with attention deficit hyperactivity disorder.

Compared the sensitivity of boys with and without attention deficit hyperactivity disorder (ADHD) to differences in reward frequency. Fifteen boys with ADHD as diagnosed in the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) and a matched control group completed a signal-detection task in which correct identification of 1 stimulus was rewarded 3 times as often as correct identification of the other. Boys in the ADHD group completed the task twice, on and off medication. Group differences emerged in response bias toward the more frequently rewarded alternative. Boys in the control group showed a stable pattern of response bias, irrespective of which alternative they were last rewarded on. Boys in the ADHD group showed different patterns of response bias following rewards on the 2 alternatives. These results suggest children with ADHD were more sensitive to individual instances of reward compared with controls, whose response bias is governed more by their reinforcement history. Methylphenidate improved discriminability and reduced sensitivity to individual instances of reward in the boys with ADHD.     

Anger control in response to verbal provocation: Effects of stimulant medication for boys with ADHD

Although stimulant medication reduces hyperactive children's aggression in naturalistic settings, stimulant effects on anger control have not been demonstrated. We therefore assessed the role of methylphenidate in enhancing response to verbal provocation from familiar peers and from role-playing adults. Twenty-four boys with attention deficithyperactivity disorder (ADHD), aged 6–12, received small-group cognitivebehavioral intervention in anger management skills. During posttraining assessments, the children were randomly assigned to placebo versus. 6 mg/kg of methylphenidate. In the peer provocations, methylphenidate enhanced self-control, decreased physical retaliation, and marginally increased the display of coping strategies. Medication and prompting were minimally beneficial in the delayed, adult-administered generalization assessments. Among the issues discussed are (a) differences between peer and adult provocation and (b) the roles of medication dosage and multimodality intervention for promoting socially competent behavior in children with ADHD.We gratefully acknowledge the Fernald Child Study Center of the University of California, Los Angeles, which provided major support for this research. In addition, we acknowledge the dedication of the small-group trainers, too numerous to mention individually, who led the intervention procedures for the children, and the experimenters who performed the individual provocation assessments. The careful behavior observations of Linda Douglas, Rebecca Eiser, Deborah Gibson, Mike Glenn, Melissa Michaelson, Jon Rafuse, Fauzia Simjee, Leslie Sherman, and Madelin Tundidor were central to the study. Finally, our colleagues Barbara Henker and Carol K. Whalen were instrumental in facilitating all aspects of this investigation.     

Effect of stimulant medication on lower extremity response time of boys with attention deficit hyperactivity disorder

Children with attention deficit hyperactivity disorder (ADHD) have been labeled as "inefficient movers"; however, little research has examined the effect of stimulant medication on lower extremity movements. 16 boys, 11 to 13 years old, with ADHD performed a lower-limb choice-response time task, both on and off medication. When nonmedicated, children had significantly slower reaction times to all three targets and significantly slower movement times for the contralateral and midline movements. For both conditions, children had significantly faster movement time when using the right leg than the left leg. These findings suggest that movement characteristics of children with ADHD are different under medicated and nonmedicated situations.     

Comprehension of televised stories in boys with attention deficit/hyperactivity disorder and nonreferred boys

Two studies compared comprehension of televised stories by 7- to 12-year-old boys with attention deficit/hyperactivity disorder (ADHD) and nonreferred comparison boys. Boys watched one show with toys present and one with toys absent. Visual attention was continuously recorded, and recall was tested after each show. Across studies, visual attention was high with toys absent but decreased sharply with toys present for boys with ADHD. Groups showed similar levels of cued recall of discrete units of information regardless of differences in attention. When recall tasks and television story structure required knowledge of relations among events, the reduced attention of boys with ADHD interfered with recall. Although visual attention of comparison boys also decreased to some extent with toys present, there was no such decrement in recall. Implications of the difficulties children with ADHD have in integrated story comprehension are discussed.     

The dyadic nature of social information processing in boys' reactive and proactive aggression

The correlation between boys' social cognitions and their aggressive behavior toward peers was examined as being actor driven, partner driven, or dyadic relationship driven. Eleven groups of 6 familiar boys each (N = 165 dyads) met for 5 consecutive days to participate in play sessions and social-cognitive interviews. With a variance partitioning procedure, boys' social-cognitive processes were found to vary reliably across their dyadic relationships. Furthermore, mixed models regression analyses indicated that hostile attributional biases toward a particular peer were related to directly observed reactive aggression toward that peer even after controlling for actor and partner effects, suggesting that these phenomena are dyadic or relationship oriented. On the other hand, the relation between outcome expectancies for aggression and the display of proactive aggression appeared to be more actor driven and partner driven that dyadic.     

Orienting attention via observed gaze shift evokes longer term inhibitory effects: implications for social interactions, attention, and memory

One component of successful social interactions is joint attention. It is now well established that when a gaze shift is observed, the observer's attention rapidly and automatically orients to the same location in space. It is also established that such attention shifts via gaze are relatively transient and do not evoke subsequent inhibition processes. In contrast to this conventional view, the authors conducted a series of studies that showed that these properties of gaze attention shift are not necessarily the case in all situations. The article demonstrates (a) gaze cuing over longer intervals than previously observed, (b) that these longer term effects can be inhibitory, and (c) that the longer term gaze cuing effects do not appear to be contingent on retrieval associated with a particular face identity.     

Promoting social competence and preventing childhood aggression: A framework for applying social information processing theory in intervention research

Advances in social information processing (SIP) theory have contributed to the understanding of the ways in which cognitive operations lead to aggressive behavior in childhood. Despite these advances, applying SIP theory to the design of interventions to promote social competence and prevent aggressive behavior remains in a formative stage. Few programs have explicitly applied the SIP theory. Moreover, among the relatively few programs that have used SIP as a theoretical basis, the applications of the SIP theory vary widely. This article provides a general framework for applying the SIP theory to school-based interventions. We review key elements of the SIP model and distinguish SIP from the more general social problem-solving perspective. We discuss several methodological issues in conducting the SIP intervention research.     

Race,social class,and response bias effects in grammatical processing

Black English and Standard English grammatical sentences were presented to 122 Black and White second graders in a modified cloze task. Both race and social class differences were sampled from within a single primary school, and both Black and White experimenters were utilized. No effects due to social class were found. Black subjects did better on Black English sentences than White subjects and showed fewer errors in the direction of Standard English syntax. An analysis of hit rates and false alarm rates suggested that Black subjects were more likely to emit Black English responses than White subjects but that both groups possessed equivalent sensitivity to grammatical differences. The results are not consistent with a deficit account of Black subjects' performance or with an explanation based on different dialect systems. Rather, it appears that Black and White children may differ only in their willingness to utilize specific response systems and may possess equal comprehension abilities in both dialect systems.This research was supported in part by funds made available to Bowling Green State University by NSF Institutional Grant No. GU-3619. Some of the findings were reported at the 83rd Annual Convention of the American Psychological Association, Chicago, 1975.     

Psychopathy, aggression, and the processing of emotional stimuli in non-referred girls and boys

Research shows that individuals with psychopathic traits differ in how they process negative emotional stimuli. However, it is unclear whether these differences are specific to certain types of negative emotional stimulus and whether they are more strongly associated with psychopathic traits or aggression. Further, it is not clear whether or not deficits in emotional processing generalize to females and ethnic minority individuals with psychopathic traits. In this study, we examined the emotional processing of visual stimuli using a dot-probe task in 50 non-referred girls and boys (mean age of 9.30; SD = 2.00). Overall, there was a significant association between proactive aggression and reduced responsiveness to distressing stimuli. In addition, the predicted association between psychopathic traits and reduced responsiveness to distressing stimuli was only found for children high on aggression. Also, the associations among aggression, psychopathic traits, and responsiveness to distressing stimuli did not differ for boys and girls.     

Early social attention impairments in autism: social orienting, joint attention, and attention to distress

This study investigated social attention impairments in autism (social orienting, joint attention, and attention to another's distress) and their relations to language ability. Three- to four-year-old children with autism spectrum disorder (ASD; n = 72), 3- to 4-year-old developmentally delayed children (n = 34), and 12- to 46-month-old typically developing children (n = 39), matched on mental age, were compared on measures of social orienting, joint attention, and attention to another's distress. Children with autism performed significantly worse than the comparison groups in all of these domains. Combined impairments in joint attention and social orienting were found to best distinguish young children with ASD from those without ASD. Structural equation modeling indicated that joint attention was the best predictor of concurrent language ability. Social orienting and attention to distress were indirectly related to language through their relations with joint attention. These results help to clarify the nature of social attention impairments in autism, offer clues to developmental mechanisms, and suggest targets for early intervention.     

The effects of hormones,Type A behavior pattern,and provocation on aggression in men

Thirty-eight male college students, classified as either Type A or Type B based on their Jenkins Activity Survey (JAS-T) scores, competed in a reaction time task that allowed them to administer shocks to an increasingly provocative fictitious opponent. Salivary testosterone and cortisol were measured both prior to and after the task. Aggression was defined as the level of shock the subject was willing to set for the opponent. The results of this study indicate that a relationship exists between endogenous testosterone levels in men and direct physical aggression. Some evidence for the moderating effects of hormones on the level of aggression expressed by Type As was observed. No direct relationship between Type A and aggression was found.     

The effects of methylphenidate on levels of processing and laterality in children with attention deficit disorder

Effects of stimulant medication (methylphenidate) on levels (feature, name, semantic) of word processing by the left and right hemisphere were assessed in 31 attention- deficit- disordered children. In a double-blind procedure, same- different decisions were made to tachistoscopically presented word pairs under medication and placebo. Analysis of manual response times failed to show any negative effects of medication. Feature decisions were faster than name decisions, which were faster than semantic decisions. Methylphenidate induced a right visual field advantage (left hemisphere) for the name decision, which was interpreted as a normalization effect. The results suggest that (1) methylphenidate may selectively improve the phonological level of word processing and (2) methylphenidate's favorable therapeutic effect is produced through inhibition of excessive right hemisphere activity in response to task demands that engage the left hemisphere.This research is based in part upon a doctoral thesis completed by the first author in the Department of Education, University of Toronto. The authors thank Dr. William Logan and Dr. Wendy Roberts of the Hospital for Sick Children for permitting testing of patients in the Child Development Clinic. This research was supported in part by a doctoral fellowship from the Social Sciences and Humanities Research Council to the first author.     

The effects of divided attention on information processing in manual tracking.

Six subjects performed a manual tracking task concurrently uith each of two secondary tasks: in input task (auditory signal detection) and an output task (application of a constant force). A feedback-control analysis of tracking performance was utilized to analyze the time-sharing decrements observed in mean squared errer, in terms of components due to processing delay, addition of internal processing noise, and change in response bias (tracking gain). The results indicated that only the parameters measuring noise and gain were sensitive to time-sharing conditions, and these only to concurrent performance of the force application task. It is concluded that limits of attention in dual-task performance are more severe in output than in input stages of processing, but that these limits are not necessarily those of a single-channel bottleneck. Instead, a broader conception of attention is proposed: one that included changes in processing noise and shifts in response bias, as attention-related phenomena.     

Aggression and heat: mediating effects of prior provocation and exposure to an aggressive model.

Sixty-four undergraduate males participated in an experiment designed to examine the effects of level of prior anger arousal, exposure to an aggressive model, and ambient temperature on physical aggression. On the basis of Bandura's social learning theory of aggression, it was predicted that uncomfortably hot environmental conditions would be most effective in facilitating later aggression when subjects had both witnessed the actions of the model and been exposed to strong provocation from the victim, but least effective in this regard when they had neither witnessed the actions of the model nor been exposed to prior instigation. In contrast to these predictions, results indicated that high ambient temperatures facilitated aggression by nonangered subjects but actually inhibited such behavior by those who had previously been provoked.     

Integrating biological and social processes in relation to early-onset persistent aggression in boys and girls

This study examined the relationship between biological and social risk factors and aggressive behavior patterns in an Australian high-risk sample of 370 adolescents. Perinatal, temperamental, familial, sociodemographic, and behavioral data were collected during interviews completed during pregnancy. immediately postpartum, and when the children were 6 months old and 5, 14, and 15 years old. Youths were given tests of verbal and neuropsychological functioning at the age 5 and age 15 follow-ups. Youths were divided into early-onset persistent aggression, adolescent-onset aggression, and nonaggressive behavior groups. Results revealed that the interaction of biological and social risk factors was significantly related to early-onset persistent aggression. Gender and developmental phase of measurement moderated the relationship between biosocial risks and the outcomes of early-onset persistent aggression and adolescent-onset aggression.     

Methylphenidate in hyperactive children: Differential effects of dose on academic,learning, and social behavior

Methylphenidate (Ritalin) has been shown to have differential effects on hyperactive children's behavior as a function of dose level. In the present investigation, a triple-blind, placebo-control, within-subject (crossover) experimental design was employed in which 12 hyperactive boys between 6 and 10 years received three different dosages of methylphenidate (5, 10, and 15 mg) in a randomly assigned sequence. Dosage effects were assessed on clinic(PAL-Paired Associates Learning test) and school-(percent on task, teacher ratings, work completion rates, and accuracy) related behaviors. For 10 of the children, classified as responders to medication by the PAL using the criteria of Swanson, Kinsbourne, and colleagues, a series of ANCOVAs with repeated measures showed significant dosage effects on teacher ratings (p 01), percent on task (p 01), academic accuracy (p 05), and assignment completion rates (p 05). PAL performance was also significantly enhanced (p 01) after optimal dose levels were considered. Subsequent trend analysis showed a significant positive linear relationship between dose and each of the dependent variables. A comparison of fixed-dose and miligram-per-kilogram plots showed that children's performance across the different dosages were clearly individualistic and task-specific, even when similar body weights were compared. The implications of using clinic-based testing to determine optimal medication responsivity were discussed.We would like to express our sincere appreciation to the following pediatricians for their valuable assistance: W.

Good friendships,bad friends: Friendship factors as moderators of the relation between aggression and social information processing

The primary objective was to examine whether the associations between aggression and social information processing was moderated by friendship quality and the aggressiveness of the best friend. Drawn from a larger normative sample of 5th and 6th graders, 385 children (180 boys) completed questionnaires pertaining to friendship quality and social information processing. Friendship and peer nominations of behaviours were collected. Results revealed positive associations between aggressive behaviour and the endorsement of aggressive coping strategies in cases where the protagonist was an unfamiliar peer. However, one important exception emerged: no significant associations between aggression and aggressive coping were revealed for children with high-quality friendships with aggressive peers. In cases where the protagonist was the best friend, there was a significant relation between aggression and vengeful coping, but only for those participants who had a low-quality friendship with an aggressive friend.
